The singer, 34, spilled the beans about new-mom lunch dates with her former Destiny’s Child band members — and they now involve their active little tots.

“Just the other day we were all able to sit down and have lunch together, and that always feels good,” Rowland said during an interview on the Meredith Vieira Show on Tuesday, also mentioning that her pal Beyoncé brought along 3-year-oldBlue Ivy to play with her 4-month-old sonTitan Jewell.

But she admitted that the catch-up sessions have quickly turned into toddler time. “Titan’s screaming and Blue is probably climbing something,” she joked to talk show host Meredith Vieira.

The old friends still manage to squeeze in some baby-free nights out on the town.

Now the mom of three has officially launched her line, King of Harts, just in time for the warmer weather — and we couldn’t be more excited.

The actress, 38, has made her designing debut in the kiddie market with a sea of surfer-inspired duds — including chic button-downs, cargo shorts and fun graphic tees — that have already received the seal of approval from Hart and husband Mark Wilkerson‘s three boys, Tucker, 2½, Brady, 7, and Mason, 9.

After the launch, the mom of three caught up with PEOPLE to discuss everything from the adorable collection and her boys’ favorite pieces to clothing wars and her sons’ recent milestones.

After hanging out at the Marquee Dayclub in Las Vegas, the reality star took to Instagram on Saturday to show her fans how she manages to continue nursing 3-month-old sonReign Aston even when she’s away from home.

“After the show it’s the after party,” she captioned the shot of her pumping in a breastfeeding-friendly bra.

In addition to spotlighting her nursing skills, Kardashian, 35, also showed off her svelte body after baby in matching black undergarments.

“3 years buddy! 3 beautiful years! You make every minute worth while! We cherish all your firsts and all that is to come,” she wrote. “Happy 3rd birthday my love #timesflying #whatayear.”

The 27-year-old included her soon-to-be ex-husbandMike Comrie in the Flipagram pics, which show Luca enjoying time in the sun and snow with both his mom and dad.

Duff and Comrie, 34, announced their separation after five years of marriage in January 2014, and the actress and singer reportedly filed for divorce in February 2015, shortly after rumors swirled about the former NHL player having a wild night out with friends in Beverly Hills, California.
